Week 3 Refrigerant

This week we worked more on refrigerant and actually using our machines to reclaim and recharge the refrigerant from 2 different trucks. The refrigerant flow and all of the components actually click for me this week so I feel a lot more confidant in the A/C platform.

 In this picture is the standalone A/C circuit That we used to identify all of the components and the flow of refrigerant. The unit made it easy to identify High and low pressure lines and all of the components like Accumulator on a system will always have a Orifice Tube and a receiver dryer will have a expansion valve in the system. In the back of this picture Mick is showing us how to operate the rotary machine that acts as a drill or can rotate cylinder objects.

This is a fifth-wheel coupling or a Fifth axel. During this time I had always thought that the grease on these were meant to prevent rust and that why it was spread. Mick instructed us that it's used to prevent the axel from seizing. It has to be cleaned on maintenance intervals.

This whole week was really good for me, everything starting piecing together and I actually started to understand. Id like to keep up working on A/C components so I don't lose this knowledge.
